DRAFT-RIGGING.-

Specification of Letters Patent.

Application filed October 6, 1908.

Patented J'une29, 1909. Serial No. 456,298.

To all whom it may concern:

company ng drawings, forming part of this specificatio My invention relates to a draft rigging for use upon railway cars, the invention having for its ob'ect the construction of a draft rigging of t e character named in which the draw bar is so supported as to be capable of an easy movement in an arc of a circle when a car equipped with the rigging and connected to another car is rounding a curve in a railway track. 3 f

Figure I is a top or plan view of my draft rigging a plied to the center sills of a railway car. 1g. II is a side elevation of the rig ing. Fig. III is an enlarged view showing the raw bar and the draw bar stirrup in plan and the tracks on which said stirrup operates in horizontal section. FigIV ism part an enlarged side elevation of the draw bar and in part an enlarged vertical longitudinal section taken through the draw bar stirrup and the track rails on which said stirrup o erates: Fig. V is a vertical cross sectionfta en on irregular l ne VV, Fig. IV. the accompanying drawings: A designates the center sills of a railway car and B a draw-bar that may be of any common construction.

io The-forward end of the 1 designates a pivot block that is secured to the center sills and to which the rear end of the draw bar is connectedby a-pivot pin 2-. draw bar, includin the coupler head and its shank B, is free 0 positive connection to the center sills or other parts of the car underframe and is therefore susceptible of movement in an arc of a circle In Q1 laterally relative to a longitudinal line through the center of a'car to which my draft rigging is applied.

' 3 designates segment shaped track rails .50 that are secured tothe center sills A at their er that the coupler head may travel lower sides and which extend laterally from said center sills. These rails are of Z-sha e in cross section to provide for their attac e ment to the center sills and to furnish runways 4 that are located beneath the center sills and are sufficiently separated from each other to rovide a passageway between them.

5 is a raw bar carry stirrup that loosely oncircles the coupler head shank B ofthe draw, bar B and is referably composed of sections bolted to eacli other in order that said stirrup may be readily fitted around the draw bar 01 separated therefrom without-the'necessit of disconnecting the parts of the draw ar. The draw bar carry stirrup is provided at Its travel in the passageway between t 6 run way ledges of the track rails 3, and this head. has mounted in it a bearing shaft 7 that projects beyond the sides of the head.

It is desirable to maintain the draw bar of my draft rigging in a permanent position and to prevent as ateral movement thereof during 1 the shipment of a car to which therigging has been applied, and to provide for the draw bar being so held, I attach to one of the track rails 3 of the rigging a restraining stirmp 9. This restraining stirrup embraces the coupler head shank of the draw baiand is connected to the track rail 3 towvhich it is applied-by a pin or bolt IO' th'n't asses t rough lugs 3* project' from .sai rail.
